Comparative Analysis of the Subventricular Zone in Rat, Ferret and Macaque: Evidence for an Outer Subventricular Zone in Rodents

The mammalian cerebral cortex arises from precursor cells that reside in a proliferative region surrounding the lateral ventricles of the developing brain. Recent work has shown that precursor cells in the subventricular zone (SVZ) provide a major contribution to prenatal cortical neurogenesis, and that the SVZ is significantly thicker in gyrencephalic mammals such as primates than it is in lissencephalic mammals including rodents. Identifying characteristics that are shared by or that distinguish cortical precursor cells across mammalian species will shed light on factors that regulate cortical neurogenesis and may point toward mechanisms that underlie the evolutionary expansion of the neocortex in gyrencephalic mammals. We immunostained sections of the developing cerebral cortex from lissencephalic rats, and from gyrencephalic ferrets and macaques to compare the distribution of precursor cell types in each species. We also performed time-lapse imaging of precursor cells in the developing rat neocortex. We show that the distribution of Pax6+ and Tbr2+ precursor cells is similar in lissencephalic rat and gyrencephalic ferret, and different in the gyrencephalic cortex of macaque. We show that mitotic Pax6+ translocating radial glial cells (tRG) are present in the cerebral cortex of each species during and after neurogenesis, demonstrating that the function of Pax6+ tRG cells is not restricted to neurogenesis. Furthermore, we show that Olig2 expression distinguishes two distinct subtypes of Pax6+ tRG cells. Finally we present a novel method for discriminating the inner and outer SVZ across mammalian species and show that the key cytoarchitectural features and cell types that define the outer SVZ in developing primates are present in the developing rat neocortex. Our data demonstrate that the developing rat cerebral cortex possesses an outer subventricular zone during late stages of cortical neurogenesis and that the developing rodent cortex shares important features with that of primates

Experimental clinical substantiation of application of immobilized forms of sodium hypochlorite in treatment of infected pancreatonecrosis

OBJECTIVE. The study substantiated the possibility of application of sodium hypochlorite for treatment of infected pancreatonecrosis. MATERIAL AND METHODS. The experimental study was conducted on 288 rats. Clinical research was carried out on 94 patients who were divided into two statistically homogenous groups. «Levomecol» ointment was used in the first group for sanation of omental bursae (lesser sac). The immobilized form of sodium hypochlorite was applied for the second group. RESULTS. Anti-inflammatory activity of immobilized form of sodium hypochlorite exceeded this activity in case of «Levomecol» application in 1,2-1,4 times. Anti-microbial activity was higher in 1,6-1,8 times at different terms of treatment of experimental animals. The proposed method of treatment of infected pancreatonecrosis allowed doctors to decrease the number of postoperative complications in patients on 11,2 % and lethality - on 9,2 %. CONCLUSIONS. It was stated that the application of immobilized forms of sodium hypochlorite for sanation of the omental bursae was pathogenically justified and efficient
